Laravel :: Best way to update a foreign key

Question

I have this migration file

Schema::create(\'table_one\', function(Blueprint $table) 
{ 
    $table->increments(\'id\'); 
    $table->string(\'name\');          


        

Answer 1

Drop the foreign key then add it again and run migrate.

public function up()
{
    Schema::table('table_one', function (Blueprint $table) {
        $table->dropForeign(['table_two_id']);

        $table->foreign('table_two_id')
            ->references('id')
            ->on('table_two')
            ->onDelete('cascade');
    });
}
